IMPROVEMENT IN BORED AND DRIVEN WELLS.

` Specification forming part of Letters PaftentNo. 2h5,238, dated May13, 1879;. application iiled June 4, 1ers.

To all whom it 'may concern:

Be it known that we, JOSEPH F. PHLLOW,

of Warsaw, Kosciusko county, and PALMER C. PERKINS, of Mishawaka, St.Joseph county, State of Indiana, have invented a new and useful'Improvement in Bored and I Driven Wells, of which the following is afulldescription, reference being had to the accompanying drawings, in which-Figure l is avertical section; Fig. 2, a side elelvation of thevalve-section, and Fig. 3 a detai.

This invention relates to bored and driven wells, having for its objectto improve the same, and furnish a device that is not liable to get outof repair, and which'can be conveniently used, as will be hereinaftermore fully described, and pointed'out by the claim. In the drawings, Arepresents'the main tube. 0n its lower end is a steel coupling, a, whichis a little. larger than the other couplings, to facilitate. theirpassage.l

B is the strainer.A (lis a secondary tube, which may be called thestrainer-tube. It is connected to the strainer by means of a suitablecoupling, and, as shown, there is another coupling at the upper end.`rllhis tube C is to b' of any required length, and is especially esignedto pass from some loose lower strata up through a hard strata, there tomeet the main pipe.

bis a coupling upon the upper ehd of '0. Asshown, this coupling isbeveled at the top on the inside.

, D is a ball-va1ve, placed in an open charn-v ber, as usual. E is astem, the upperv end ofA which formsA the valve-seat. F is a bail,connected with the stem E by a'screw-thread. -c is a shoulder on'thestem E. G is a packing, of rubber or other suitable flexible material.It surrounds the stem, and its lower end rests upon the shoulder c,-but4 the packing `is of such thickness that it projects a little beyondthis shoulder. A

dis a metal ring or washer, resting on the packing G. The lower end', g,of the stem E extends downward below the packing, and, as shown, isbeveled to iit into the coupling l).

c is a lug or pin on the stern E, and f is a corresponding slot in thecoupling b.

In use the main tube or pipe A is to be driven to place, and thestrainerB and strainer-tube, when used, are to be placed at the bottomof the well, the upper end being within the main tube. Then the. valve,with the stem, bail, and packing, is to be dropped orl lowered to place,the packing being next compressed, and the stein E entering the coupling or collar b. Then, by means of a suitable tool engaging' withthebail F, this bail can be rotated, carrying with it the stem, untilthe pin e drops into the notch or slotf, after which .the packing can becompressed by turning the bail .until it fills the space between themain tube and stem, forming a tight'joint. At the same time the loweredge of the packingwillA rest upon the top of the coupling b, making atight joint at that point, preventing the passage of sand or grit to themain pipe at this point.

What we claim as new is as follows: The'stem E, having an extension, g,proA vided with. a pin, e, in combination with a flexible packing, G,bail F, main tube A, and a coupling or tube adapted to receive the end gof the 4stern andthe pin e, all constructed and .operating substantiallyas and for the.

purposes specified.
